DevOps means a concept to bring Development team and operation team together. So that you can speed up the deployment process.

The best Free mining tool that adds value to backup data

The next big thing in backup will be a business use case to mine
the data being stored for useful information. It’s a shame all that data is
just sitting there wasted unless a restore is required. It should be leveraged
for other, more important things. This method is called Data Mining Technique.

For example, can you tell me how many instances of any single file
is being stored across your organization? Probably not, but if it’s being
backed up to a single-instance repository, the repository stores a single copy
of that file object, and the index in the repository has the links and metadata
about where the file came from and how many redundant copies exist.

By simply providing a search function into the repository, you
would instantly be able to find out how many duplicate copies exist for every
file you are backing up, and where they are coming from.
Knowing this information would give you a good idea of where to go
to delete stale or useless data. The complete knowledge on Data mining is a plus point to start further on this. After all, the best way to solve the data
sprawl issue in the first place is to delete any data that is either duplicate
or not otherwise needed or valuable. Knowing what data is a good candidate to
delete has always been the problem.

Tools available

I think there may be an opportunity to leverage those backups for
some useful information. When you combine disk-based backup with data
deduplication, the result is a single instance of all the valuable data in the
organization. I can’t think of a better, more complete data source for mining.

With the right tools, the backup management team could analyze all
kinds of useful information for the benefit of the organization, and the
business value would be compelling since the data is already there, and the
storage has already been purchased.

The recent move away from tape backup to disk-based deduplication
solutions for backup makes all this possible.

Being able to visualize the data from the backups would provide
some unique insights. As an example, using the freeWinDirStat tool

A best use case is, I noticed I am backing up multiple copies of
my archived Outlook file, which in my case is more than 14GB in size. If you
have an organization of hundreds or thousands of people similar to me, that adds
up fast.

The below are the best questions to use Data Mining tool

Are you absolutely sure you are not storing and backing up
anyone’s MP3 files? How about system backups? Do any of your backups contain
unneeded swap files? How about stale log dumps from the database administrator
(DBA) community? What about any useless TempDB data from the Oracle guys? Are
you spending money on other solutions to find this information? Are you
purchasing expensive tools for email compliance or audits?

Advantages of Data
mining

The backup data could become a useful source for data mining,
compliance and data archiving or data backup, and can also bring efficiency into data storage
and data movement across the entire organization.
